JOHN J. SCHLUETER, OF SAN FRANCISCO, CALIFORNIA.

DOOR-CH ECK.

SPECIFICATION formingpart of Letters Patent No. 242,057, dated May 24, 1881. Application filed February 12, 1881. (No model.)

To all whom it may concern:

Be it known that I, JOHN J. SCHLUETER, of San Francisco, in the county of San Francisco and State of California, have invented a new and Improved Door-Stop, of which the following is a full, clear, and exact description.

The object of this invention is to provide a simple and convenient device for preventing a door from swinging back against the wall and for holding the door open.

Figure l is a sectional elevation, showing the door knob and plate in position. Fig. 2 is a longitudinal section of the door-stop. Fig. 3 is a longitudinal elevation of the same. Fig. 4 is a front-end elevation of the door-stop. Fig. 5 is a front elevation of the door knob and plate.

Similar letters of reference indicate corresponding parts.

In the drawings, Arepresents a dished plate, provided with a knob, B, projecting from its concave face, beyond the plane thereof, and secured to the door C by screws a, that pass through the plate-flange b.

D is the door-stop, provided at one end with a projecting screw, D, by means of which it is fastened to the base-board or wall of a room. The opposite end of said stop D is socketed, as shown at E,to receive the knob B, and fixed in'the body of the stop D, in the bottom of the socket E, is a block or cushion, H, of rubber or other elastic substance, that is designed to prevent noise on the entrance of the knob B into the said socket E.

On opposite sides of the stop D two springs, F F, are sunk in corresponding sockets G G,

that extend longitudinally along the said stop D, and are secured in place by screws 0, that pass through their inner ends intosaid stop D. The free ends of said springs F are thickened and curved inward toward each other over the lips of the socket E, leaving space enough, however, between them for the entrance of the point ofthe knob B, which point being slightly conical, as shown at d, forces said springs F F apart on contact therewith and enters the socket E until it strikes the cushion H, when the said springs F F close behind the shoulderf of said knob B, and thereby hold it and the door to which it is attached fast. The free ends of the springs F F being rounded on the inside, as shown at h, a slight pull on the door C will release the knob B from said springs F F, so that the said door 0 may be closed.

I am aware that door-stops provided with spring-catches have heretofore been used but I am not aware that any have been constructed like the one herein shown and described.

Having thus described my invention, I claim as new and desire to secure by Letters Patent The combination, with the dished door-plate A, having slightly conical knob B, of the stop D, having a screw, D, socket E, cushion H, projecting into the middle of socket, and the two opposite side springs, F F, curved toward each otherat their free ends, as shown and described.
